Description

Glass cement production line piston accumulator

Technical field

This utility model relates to a kind of multi-piston type accumulator, it particularly relates to a kind of structure letter Single, prevent liquid gas from altering mutually, it is ensured that the glass cement production line piston type accumulation of energy of long-time normal work Device.

Background technology

Existing accumulator seals structure: double Yx enclose+AQ seal structure, i.e. nitrogen medium end and hydraulic pressure Media end all seals as first with Yx circle, and leaking medium pressure is sealed as second by AQ again Seal, it is ensured that accumulator liquid gas can not be altered mutually；Yx loop material is PU or NBR, and AQ closure material is NBR+PTFE, material is the softest, and glass cement has the strongest adhesiveness, during accumulator work, Because its system pressure is relatively low, softer, and in cylinder barrel due to material for 3-5MPa, Yx circle and AQ envelope Surface Mount is made a concerted effort not, it is impossible to is removed by the glass cement of cylinder barrel inner surface clean, causes accumulator liquid gas Alter mutually, it is impossible to normally work, a kind of glass cement production line that can effectively prevent liquid gas from altering mutually It it is the key solving the problems referred to above with piston accumulator.

Utility model content

For above deficiency, this utility model provides a kind of simple in construction, prevents liquid gas from altering mutually, Ensure the glass cement production line piston accumulator of long-time normal work, including cylinder barrel, piston With within black box, piston and black box are arranged on cylinder barrel, piston is fixing with black box even Connecing, black box includes Yx circle, AQ envelope, antifriction alloy ring and two support rings, Yx circle, One support ring, AQ envelope, another support ring and antifriction alloy ring are successively set on piston and cylinder barrel Contact surface on.

For realizing this utility model further, cylinder barrel is divided into nitrogen chamber and hydraulic cavities by piston.

For realizing this utility model further, Yx circle is the first sealing ring in nitrogen chamber, resistance to break-in Jin Huan is the first sealing ring of hydraulic cavities.

For realizing this utility model further, alloy wear-resisting ring is elastic construction.

For realizing this utility model further, the material of antifriction alloy ring is alloy cast iron.

For realizing this utility model further, the inner chamber of cylinder barrel is cylindrical structure.

The beneficial effects of the utility model:

1, glass cement production line piston accumulator of the present utility model, including cylinder barrel, piston and Within black box, piston and black box are arranged on cylinder barrel, the inner chamber of cylinder barrel is cylindrical structure, Piston and black box are fixing to be connected, black box include Yx circle, AQ seal, antifriction alloy ring and Two support rings, Yx circle, support ring, AQ envelope, another support ring and antifriction alloy ring Being successively set on the contact surface of piston and cylinder barrel, cylinder barrel is divided into nitrogen chamber and hydraulic cavities by piston, Yx circle is the first sealing ring in nitrogen chamber, and antifriction alloy ring is the first sealing ring of hydraulic cavities, During work, sealing surface generation elastic deformation will not be made because of the resistance of glass cement and viscosity, therefore can have Effect seal glass glue and the glass glued membrane of removing cylinder barrel inner surface, prevent accumulator liquid gas from altering phenomenon mutually, Ensure that accumulator can the most normally work.

2, glass cement production line piston accumulator of the present utility model, alloy wear-resisting ring is elastic Structure, when using as sealing member, its periphery and inner hole of cylinder can be tightly under elastic force effect Fit together.

3, glass cement production line piston accumulator of the present utility model, the material of antifriction alloy ring For alloy cast iron, during the work of antifriction alloy ring, sealing will not be made because of the resistance of glass cement and viscosity Face occur elastic deformation, therefore can effectively seal glass glue and removing cylinder barrel inner surface glass glued membrane, Prevent accumulator liquid gas from altering phenomenon mutually, it is ensured that accumulator can the most normally work.

Accompanying drawing explanation

Fig. 1 is the sectional view of glass cement production line piston accumulator of the present utility model；

Fig. 2 is the office of the black box of glass cement production line piston accumulator of the present utility model Portion's drawing.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further elaborated, wherein, of the present utility model Direction is with Fig. 1 as standard.

As it is shown in figure 1, glass cement production line piston accumulator of the present utility model, including cylinder Cylinder 1, piston 2 and black box 3, wherein,

Cylinder barrel 1 uses general structure, and its inner chamber is cylindrical structure, cylinder barrel 1 horizontally set；

Within piston 2 is arranged on cylinder barrel 1, the inner diameter of the diameter correspondence cylinder barrel 1 of piston 2 sets Putting and be in close contact with the inwall of piston 2, cylinder barrel 1 is divided into two cavitys by piston 2, and it is left End is nitrogen chamber 4, and right-hand member is hydraulic cavities 5, and piston 2 can be along the inwall of cylinder barrel 1 in certain limit Inside horizontally slipping, piston 2 is provided with groove corresponding to the position of black box 3；

Within black box 3 is arranged on cylinder barrel 1, black box 3 is fixing with piston 2 to be connected and right The groove answering piston 2 is arranged, and black box 3 includes Yx circle 31, AQ envelope 32, antifriction alloy Ring 33 and two support rings 34, Yx enclose 31, support ring 34, AQ envelope 32, another Carrier ring 34 and antifriction alloy ring 33 are the most once arranged on connecing between piston 2 and cylinder barrel 1 In contacting surface, Yx circle 31 is the first sealing ring of nitrogen medium end, and antifriction alloy ring 33 is hydraulic pressure The first sealing ring of media end, AQ envelope 32 is second sealing ring, and the material of Yx circle 31 is The material of PU or NBR, AQ envelope 32 is NBR+PTFE, and the material of antifriction alloy ring 33 is for closing Gold cast iron, alloy wear-resisting ring 33 is extremely low because of coefficient of friction, the most easy to wear when using as sealing member, Alloy wear-resisting ring 33 has elasticity because of itself, its periphery and cylinder barrel 1 endoporus energy under elastic force effect Fit tightly on together, owing to its material is alloy cast iron, during work, will not be because of glass cement Resistance and viscosity, make sealing surface generation elastic deformation, thus can effective seal glass glue, and can remove The glass glued membrane of cylinder barrel 1 inner surface, prevents accumulator liquid gas from altering phenomenon mutually, it is ensured that accumulator can be grown Time normally works.

The foregoing is only better embodiment of the present utility model, the invention is not limited in above-mentioned Embodiment, there may be the structural modification that local is small, if to this practicality in implementation process Novel various changes or modification are without departing from spirit and scope of the present utility model, and belong to this practicality Within the scope of novel claim and equivalent technologies, then this utility model is also intended to comprise these and changes Move and modification.
